This is an optional excursion as it’s a 25 minute walk down Champs-Élysées. Alternatively, you can hop on the Metro, line 1 at Champs-Élysées - Clemenceau and take it 3 stops to Charles de Gualle - Étoile for a total of 15 minutes to the Arc. The Arc de Triomphe honors those who fought for France in the French Revolutionary and Napoleonic Wars and beneath it lies the Tomb of the Unknown Soldier from WWI. An eternal flame burns in memory of the dead who were never identified. It is one of the most famous monuments in Paris after the Eiffel Tower and also has one of the best views of this beautiful city. As you stand at the top of the 164ft. monument (but be prepared to climb the 284 steps) you can clearly see how all the avenues come together at the Arc. You can also get a pretty killer shot of the Eiffel Tower from up there!
